iFit/cumsum

PURPOSE

s = cumsum(a,dim) : computes the cumulative sum of iData objects elements

SYNOPSIS

function [b,sigma] = cumsum(a,dim)

DESCRIPTION

 s = cumsum(a,dim) : computes the cumulative sum of iData objects elements

   @iData/cumsum function to compute the cumulative sum of the elements of the data set
     cumsum(a,dim) accumulates along axis of rank dim.

 input:  a: object or array (iData)
         dim: dimension to accumulate (int)
 output: s: accumulated sum of elements (iData)
 ex:     c=cumsum(a);
